Nissan Motorsports Oil Cooler vs. Stillen Oil Cooler

lastblueprint · 11-13-2010, 11:00 PM

Also should I worry about Nissan installing my Nissan Oil Cooler? This is my situation, Nissan bought mine, will install it and will not affect my warranty. I guess I’m a little paranoid.

If Nissan is installing it and guaranteeing your warranty, you're fine.

As for an oil change, it will make no difference in terms of car care and engine longevity if you empty the cooler as well or not. If you choose to empty the cooler, you just unscrew one of the cooler hoses at the sandwich adapter by the oil filter during your oil change. If you do that, you'll add the extra quart when you replace the oil. If you don't unscrew a hose (empty the cooler), you'll just add the 5 quarts. Make sure you measure using the dipstick as '5' and '6' are ballparks.

Wow, Hey man, thanks for the info. That really helps. Now I can start taking my car to the track at Button Willow. This past week when I went to Sema, on the way there my car went on safe mode, that heat killed me. I’m glad my cooler is going to be installed this week.

So the 19 row Stillen is out of the picture for agressive street and light track and the 25 row would be better suited for that type of driving. The 34 row would be for all out track driving or if you can budget the higher cost it would also be suited for agressive street and track.

Was it ever concluded as to which oil cooler? Stillen, Nissan or GTM?

Stillen, GTM and Nissan are all using Setrab cores, the main difference is the lines, fittings and adapter plate. You definitely want the best quality lines and fittings you can find, too many failures from badly assembled lines.

^Very true, one reason why I decided on the Stillen cooler is that I could not find any reports of lines or fittings failing which swayed me.

Dustin@Z1 · 11-15-2010, 01:11 PM

If you are looking for another suitable option for an oil cooler for your 370z aside from the 3 kits listed. Take a few minutes to look over our kit.

We have worked extensively with our manufacturers and customers to create...what I believe...is the most comprehensive oil cooler kits for the 370z.

Z1 Motorsports 370z Oil Cooler Kit

We have attempted to address ALL of the issues we have found with our competitors oil cooler kits and to create a installation manual that is easy to understand and follow thru the entire installation process.

ChrisSlicks · 11-15-2010, 01:59 PM

Dustin,

Do you supply -10AN lines or -8? Your web page indicates both sizes, -8AN fittings with -10AN lines.

YEEEEEEEEEEEAAAAHHH....that's definitly my mistake.

The lines and fittings are all -10 AN on the 370z oil cooler kits.

We use a -8 AN on our 300zx kits and I guess I mixed something up in my head when I was creating the pages for both kits.

Sorry about the confusion!

BOLIO 671 · 11-17-2010, 05:03 AM

I really like the oil kits that Z1 has to offer...I'll be pulling the trigger on this real soon...The fact that you retain the OEM factory oil filter and the bigger -10 lines are a plus.

Ok guys just got my Nissan oil cooler installed by Raceway Nissan. Well I drove my car from the dealership to Beaumont and drove back to Moreno Valley through San Timoteo Canyon. I drove pretty hard, and the gauge did not move from 180 degrees. When I got back to the MV, I did a lot of stop and go because of the stop lights, it sat at 160 degrees. Is that a normal range? Now every time I push the throttle there is a whistling sound, sounds like air, is that normal as well?

One more thing, in the back of the installation guide it says
Note: This oil cooler is not thermostatically controlled and should be removed or bypass in cold temperatures.
Is this good or bad?

Josh@STILLEN · 11-18-2010, 08:06 PM

160 really is too cold. You can either try fabricating a shield in front of the cooler which has worked for some, but realistically getting a thermostatic sandwich plate and swapping it out will be the best method.

It bypasses the cooler until the temperature of the oil comes up. Too large of a cooler can overcool the oil as well, and the Nissan cooler is large. Oil that isnt up to temperature is also bad, and should be remedied.

Wow, that’s not too shabby, hey where can I buy this thermostatic sandwich plate?
I will swap it on my next oil change. Thanks for the feedback Josh.

Not to dispute what you posted Josh, but here is what Dustin@Z1 had to say about it when I asked him about the 160-ish temperatures I was seeing:

Quote:

No worries. This is perfectly normal. There is a slight flaw in the VQ37VHR's design that we have discovered. Like I have mentioned in the past, over cooling the engine oil is just as detrimental as over heating it. The general oil temp range you want to see on a properly installed oil temp gauge is between 190 ~ 210 ideally.

This engine oil temp is what you want to see COMING OUT from the motor. In the case of the 370z and any add-on oil cooler, you are actually getting a false reading. Since the factory temp gauge reads engine oil as it exits the Oil Filter, you are actually reading the oil temp coming directly from the oil cooler. The flow pattern for engine oil on a 370z is as follows:

Pick Up Tube --> Oil Pump --> Oil Filter IN --> Oil Filter Out --> Oil Cooler --> Engine Block (Temp and Pressure gauges are located in this galley)

The temp you are reading is actually what is going back INTO the engine (which is perfect). By the time it cycles thru the engine, you can expect to see engine temps in 200 degree range.

As for the thermostatic sandwich plate, it will bypass roughly 80% of the oil back into the engine when too cold. It will still flow ~ 20% thru the oil cooler (preventing air pockets from forming).

To get a TRUE Oil Temp reading, you would need to install an inline oil temp gauge coming out from the Thermostatic Sandwich plate before the oil cooler.
